UNITED STATES PATENT OFFICE" swo'raroar. nnvrca Charles M. Beyer, Orange, N. 1., asslgnor to Western Electric Company, Incorporated, New York, N. Y., a corporation of New York I Application January 12, 1943, Serial No. 472,124

Clalma, (Cl. 175-41) An object of this invention is to provide aneihcient and eflective insulator for an electrical condenser.

In accordance with one embodiment of this invention, the exposed edges of an electrical condenser body may be covered by a sheath of impregnated glass textile material and the condenser body placed in a container. The container is then filled with a suitable potting compound.

Other objects and advantages of this invention will be apparent from the following detailed description taken in conjunction with the drawing,

wherein:

Fit. 1 is a vertical section oi a condenser constructed in accordance with this invention, and Fig. 2 is a sectional view along the line 2-2 of Fig. 1.

nating a glass textile sleeving material with a ,ther'mosetting compound, such as a phenol formaldehyde varnish, and baking the impregnating material to obtain the required physical properties and shape in the material. The sheaths may also be made by tanning a tape into the quasicylindrical shape shown in cross section in Fig. 2,

' body to serve as an insulator in the same way as the strip l0. Potting 1 compound s then poured into the container to a depth sufllcient to completely immerse the condenser body.

Referring now to the drawing. an electrical condenser'constructed in accordance with one embodiment of this invention is shown comprising a laminated condenser body I oi substantially rectangular shape. Metallic clamps 8 are secured to opposite edges of the body and the upper portion of each of these metallic clamps is extended to iorm a terminal I for the condenser.

The condenser body I is adapted to be positloned in a metallic container 8. In order to insulate the condenser body from the sides of the container and to support it within the container, sheaths l are positioned over the clamps l at either side oi the condenser body. These sheaths completely enclose the clamps and at the same time engage the sides or the container adjacent the clamps, the size of the container being se- It will be apparent that by following the present invention, a considerable reduction is eflected in the amount of insulating material required to insulate a condenser body of this type. It will also be apparent that it is a much simpler manulecturing operation to apply a sheath to the edges of the condenser body, as described herein. than it is to apply insulation to the interior walls of the condenser container. This, of course, results in a considerable reduction in the cost 0! manuiacture of this type 01 condenser.

While but one embodiment of this invention has been shown and described, it will be understood that many changes and modifications may be made therein without departing from the spirit and scope of the present invention.

What is claimed is:

1. An electrical condenser comprising a condenser body having clamping terminal members along two opposed edges. a container, and a,

slotted tubular insulating member of glass textile material impregnated with a resin positioned over each of said clamping members, said container being of such width as to cause said insulating members to engage opposed sides of the container to retain said condenser body in position during assembly. v

2. An electrical condenser comprising a condenser body having clamping terminal members along two opposed edges. a container, a slotted tubular insulating member of slass textile materlal impregnated with a resin positioned over each 61' said clamping members, said container being of such width as to cause said insulatingmembeis to engage opposed sides of the container to ietein said condenser body in position during assembiy, and e. potting compound in said container embedding said condenser body.

3. An electrical condenser comprising e contamer, a condenser body in said container and is slotted tubular member of insulating materisi positioned over an exposed side edge of said body and beaming against said container, said member exerting sumcient clamping pressure on said body to retain said member in position thereon during the assembly of said body in said container.

4. An eiectricsi condenser comprising a som tainer, a condenser bodyin said container, and is slotted tubniar member of impregnated textile material positioned over an exposed side edge of essence said body bearing against said contsiner, said inember exerting sumcient clamping force on said body to retain said member in position thereon during the assembly of said body in said container.

5. An electrical condenser comprising a container, a condenser body in said container, a slotted tubular member of impregnated textile material positioned over an exposed side edge of said body bearing against said container, said member exerting suifloient clamping force on said body to retain said memberin position thereon during the assembly of said body in said contsiner, and a potting compound in said container embedding said condenser body.
